    摘要： A coplanar integrated optical waveguide electro-optical modulator comprises a substrate (1) of an electro-optic material, at least two optical waveguides (41, 42) integrated in the substrate in correspondence of a surface (71) thereof, and an electrode system (80, 90, 100; 80, 90, 900; 12-15; 120, 130, 140, 150, 160, 170) arranged on the surface for applying a modulating electric field to the waveguides suitable for causing a modulation of a refractive index of the two waveguides in a device modulation region (50). The waveguides are formed, for at least a section thereof (411, 421) in the device modulation region, in respective substrate regions (61, 62) which have electro-optic coefficients of opposite sign along an axis transversal to the waveguide sections, so that a modulating electric field of same direction and orientation in the waveguide sections causes refractive index modulations of opposite sign in the waveguide sections. Chirp-free coplanar waveguide modulators and single-drive double coplanar strip modulators can thus be obtained.

    摘要： A method and structure are disclosed with a simplified approach for fabricating a LiNbO3 wafer with Ti indiffusion wafeguide on the surface that is domain inverted. The method involves indiffusing Ti into LiNbO3 with a predefined temperature and time indiffusion range, a Li enriched and dry oxygen atmosphere, which allows making optical waveguides on the z− crystal face without any significant domain inversion occurring on the z+ face of the crystal. This allows for subsequent poling without the need of any additional removal of the thin domain inverted layer which would otherwise appear on the z+ face. Even in instance where a thin domain inversion layer is formed, it is insufficient thick to prevent poling, eliminating the need for the grinding process.

    摘要： A method of creating a varying second order non-linearity profile along a waveguide, comprising: providing a waveguide structure with a waveguiding core and a surface adjacent to the waveguiding core; structuring the surface to produce a structured surface defining a varying distance between the structured surface and the waveguiding core along the waveguide; and thermally poling the waveguide structure to generate a varying second order non-linearity profile along the waveguide-derived from the varying distance between the structured surface and the waveguiding core. By the surface structuring the modulation of the second order non-linearly induced by the thermal poling can be enhanced. The waveguide structures can be used for making a variety of quasi-phase-matched (QPM) devices.
